Richard has the same number of bookmarks as Rose. After Richard gave away 28 bookmarks and Rose threw away 16 bookmarks, the ratio of the number of Richard’s bookmarks to Rose’s was 2:5. How many bookmarks did they have in all at first?

Explanation:


(x - 28)/(x - 16) = (2)/(5)


2x - 32 = 5x - 140


3x = 108


x = 36

answer is 36
